I\'m updating an older iPhone application, and the usual \'Base SDK Missing\' pops up. When I open the project settings and try to set the \'iOS Deployment Target,\' it\'s
Change to the latest deployment target in the project settings and then reload the project. Failing that restart Xcode but this is not necessary.
Did you select "Base SDK for all configurations" in the General tab of the Project Settings to your Latest SDK as if you dont set the base SDK there then by default it will show as " < Multiple Values > ".
Cheers
To fix this error, I had to also change: Build -> Edit Active Target -> Build -> Architecture -> Base SDK
I had the same problem. but solved it this way:
Select your project in the left hand side, then select the target, and then in SUMMARY, select the deployment target.
My problem was that I had not seen this summary page, and it was so simple!
